EYEGLASSES.

Specification of Letters Patent.

Patented June 2, 1914..

Application filed September 23, 1910. Serial No. 583,401.

To all whom it may concern:

Be it known that I, HARRY NEWBOLD, a subject of the King of GreatBritain, residing at 46 and 48 Goswell road, in the county of London,England, have invented certain new and useful Improvements inEyeglasses, of which. the following is a specification.

My invention relates to improvements in eyeglasses and to that typethereof in which the guards are pivotally connected to the mounting andprovided with springs for holding them in engagement with the nose ofthe wearer.

The object of my invention is to provide a mounting wherein the guardsare operated by single actuating means whereby the pressure on bothsides of the nose is equalized.

Other objects of my invention are to pro vide means whereby the noseguards may adjust themselves to the wearers nose in two directions; toprovide means whereby the nose guards will tend to increase their gripon the nose when moved in the direction of displacement; and to providea one piece blank for manufacture of the bridge.

and lense fittings.

I attain these objects by the construction illustrated in theaccompanying drawing in which:

Figure 1, is a rear elevation of a pair of eyeglasses having myimprovements applied thereon. Fig. 2, is a sectional plan view thereof.Fig. 3, showsa one piece blank for the lens fittings and bridge members.Fig. 4, shows in perspective the blank bent to form, nose guard andlever attached. Fig. 5, is a perspective view of a modified nose guard,having bearings disposed in two planes. Fig. 6, shows a plan view of themodified nose guard pivoted on the inner edge as illustrated in Figs. Iand V. Figs. 7 and 8, show the plan view and elevation of a modifiedform of mounting with rigid bridge members.

Similar figures refer to similar parts throughout the several views.

Referring to the drawings: The two lenses a, a, are connected by meansof two bars or bridge members, I) and 0, which slide horizontally oneach other through perforated shoulders b and 0', the shoulder 12 beingsecured to the bar 6 and shoulder 0 to the bar 0. A spiral spring 6 iscoiled around the two bars forming the bridge piece and is held betweenthe two shoulders I) and 0'. The shoulders b and 0 may either be rigidlyattached to the bars 6 and 0 or may be loose thereon. Lens fitting fintegral with the bar I; and a corresponding fitting g integral with thebar 0 are formed at their lower ends with forked connections h to whichthe lenses a are attached in the usual well known manner. Uprightspindles or arbors a, i, which are mounted in bearings j and 70 upon thefittings f and 9 have lower inwardly extending cranked ends Z, Z, whichpivotally carry the guards m, m, and upper outwardly extending crankedends a, a, which constitute finger pieces for operating the spindles.These finger pieces a, a, pass through holes 0, 39, providedrespectively in the bars .7) and e and through corresponding slots 0, pin the bars 0 and b, the said holes 0 and 2) being positioned outsidethe shoulders c and b. The forked connections 71 the fitting g or f, andthe bar member 6 or 0 are preferably made from a one piece blank asshown in Fig. 3 and bent to shape as shown in Fig. 4, the lower bearingj being attached to the blank.

The operation of the parts is as follows: When the finger pieces a, a,which are nor mally pressed by the springs 6 toward their correspondinglenses as shown in the drawing, are manipulated by the wearer so as tobe drawn toward one another, the bar memhere 6 and a are extended,compressing the spiral spring e and increasing the distance between thepupillary centers of the lenses, the spindles a", 2' are rotated at thesame time in their bearing in and j causing the guard members m, m, torecede from each other. This rotary movement is communicated to thespindles i, 2', through the finger pieces n, n, contacting with theholes 0 and 39 in the bar members 7) and 0, and sliding in the slots 0and 7). The extension of the bar members and the recession of the guardspermits the eyeglasses to be placed upon the nose of the wearer. Onreleasing the pressure on the finger pieces a, a, the bridge memberscontract and the guards close together and form the necessary grip onthe nose, this being effected by the spring a forcing the finger piecestoward their corresponding lenses and rotating the nose guard spindles.

In Figs. 5 and 6 I have shown a modification of the guards m, m in whichthe horizontal bearing shoulder is made separate from the back of theguard, in the form of a spider member 1" provided with vertical integralpintles which engage the bearings s on the guards m, m and allow theguards to rotate in a vertical plane. The guards are thus permitted toadjust themselves tothe irregularities of the nose in both thehorizontal and the vertical planes. By placing the pivot bearin s s onthe inner edge of the guards as shown in Fig. 6, the'free edges of theguards will catch the flesh of the nose when the eyeglasses are pulledaway from the face of the wearer and the outer edges turn toward eachother about thebearings s and increase their grip on the nose.

In Figs. 7 and 8 I have shown a modification wherein the bars 5 and care combined in one piece and the lenses (1, a rigidly connected. i heholes 0 and g) and the slots 0 and p are omitted and the finger piecesn, n, are not brought into contact wit-h the bar members or bridge, butpass freely thereover and engage the ends of the spring e thereon. Inthis construction the papillary distance between the lenses remainsfixed and the glasses are adjusted by the recession of the guards at, malone as previously described.

In Fig. 3 I have shown a method of cutting out a blank from a flat sheetwhich can be bent to shape to form the forked members it, the fittingsg, f, and the bar members 6, 0, as shown in Fig. 4.

Eyeglass fittings made as above described possess a number of advantagesin practice. For example, when the finger pieces are pressed toward eachother as above described, the guards open out by the action of a sin glespring so that unequal pressure upon the two guards can not occur as ispossible where each guard is fitted with an independent spring. Thedouble ofiset bearings of the nose guards permit them to adjustthemselves to uneven contours in both directions, and provide anautomatic tightening device to resist unintentional displacement of heeyeglasses, while the one piece blank facilitates and cheapens themanufacture of the fittings.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:
